ZMD	File extension: ZMD

What is a ZMD file

ZMD files mostly belong to BlueZone. A ZMD file can serve more than one specialized purpose.
In many cases it is used as a session configuration file. For example, BlueZone and ZOC use these files to store terminal parameters such as connection settings and screen layouts. These settings help maintain a stable connection with mainframe systems.
Other instances include files used in gaming contexts.

3D Model File: Some ZMD files hold model data used in games like Dave Mirra Freestyle BMX 2.

Sega Mega Drive ROM Image: Other ZMD files are compressed images of Sega Genesis games and may be used with emulators such as those referenced on the Gens/GS platform or MAME.

FilExt.com tip: To view or edit a ZMD file, it is best to use the specific application that created it. This means using terminal emulation software for BlueZone/ZOC profiles or a game emulator/asset viewer for game files.

How to open ZMD files

You need a suitable software like BlueZone to open a ZMD file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your ZMD file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a ZMD file directly in the browser:. Just drag the file onto this browser window and drop it.

ZMD file format:

To view or edit ZMD files you need to know the file format, because it determines how the data in this file is stored. The file format can be determined based on the file extension and the signature (the first few characters of a file). However, different programs can use the same file extension, and file extensions can be assigned incorrectly. Knowledge is power - this also applies when dealing with unknown or faulty files. Our examination of the ZMD files comes to the following conclusion:

ZMD is not a commonly used file extension and includes different formats for the applicable programs. But the following two file formats are common:

• 30% of all ZMD files start with the bytes ; BlueZone Mainframe Display v crucial for this file format. The contents of these files are easily readable with a text editor. ZMD files can be up to 130 KB in size, but are often around 33 KB - 50 KB. The file type is relatively new. The keywords Enable Network DDE=0, [API], Multiple Connections=1, Enable DDE=0, Auto-Assign=1, Long Name="SessionA", Short Name="A", DOS HLLAPI=0, Trace DDE=0x0000000, ; BlueZone Mainframe Display v7.1 - Profile, BlueZone Mainframe Display v6 and Trace DDE=0x00000000 are typical for these files. The following filename is common: FedEx LSSI Screens.zmd or FAMIS-R.zmd. These files are attributed to screens, lssi, famis and screen.
• 20% of all ZMD files start with the bytes BZMD215AK, which are crucial for this file format. They consist of unreadable binary data. Most of these files are 59 KB to 140 KB in size. The files contain the following words: APIV, BZMD215AK, Enable DDE, Enable Network DDE, Long Name, Short Name, Auto-Assign, DOS HLLAPI, SessionA, Trace DDE, Trace HLL and Multiple Connections. An example of a file name is Amb_cloud_Prod_Screen.zmd or apac3270.zmd. Files like these are about prod and cloud.

The remaining 50% of all ZMD files are files with no common format, often, for example, ZIP, XML, MODL, HHh and LGZ. Tagged as ninjas, back, kick, harimanada, kombat or mortal. Just click the "Choose your .zmd file to analyze" button on this page to find out what your ZMD file is.
